This isn't Urban in the least bit but I thought that the SSP community might have some opinions and talking points to cast around about Earthships and Biotecture.
Earthships are self sustaining homes, built with recycled goods while employing solar and wind power for the house as well as utilizing water techniques that reclaim and re-use water.
Some of the places have wierd designs
Has anyone ever dealt with or actually visited one of these things? What are they like?
